Fig. i's a plan showing a sink installed in accordance with my invention in al wall 55 an i Fig. 6 is a` vertical section on line 6 -6 To all whom t may concern.: 1 Be it known that I,.JAMns F. LANesToN,

a citizen ofthe United States, residing in Lancaster, county of Los Angeles, State of California, have invented new and useful Improvements iii Cabinet Flumbing, of which the following is a specification.

This invention relates to various plumb ing fixtures, such for instance, 'as toilets, sinks, lavatories, etc: and aprimary object of the inventionis` to provide for placing such fixtures out of sight and out of the way wheirnot in use. It is not only an object to rut the toilet for instance, out vof sight w en not` in use but also to take it lout or move it out of a bathroom, for instance, and thus make more lioorspace available for general usage. This is also true of sinks, lavatories, etc.

" The advantages flowing from the accomplishments of such objects of invention will be readily understood without the necessity cfmy explaining in detail just how the i'Iivention is applied to its various cases Accordingly, as illustrative of the mvention, I, explain it inconnection with a toilet and in connectionwith a sink. Also it will be readily understood that ,the space into which the article is put when not in use may be a space enclosedwithin-a special structure, as for instance, a special cabinet built for this purpose; or it may be a space within a wall or other part ofthe building structure; onit may be a space providedpartially in both of these ways.. As a matter of illustration of my invention I show the two articles herein described as being norinallyLhoused in a wall space.

With these preliminaries in mind the invention will be best/understood from the following detailed description of illustra- ,tive and speciic 'forms of devices that embody the invention, reference forthis purpose being had to the accompanying drawings in Which- Y Figi is a vertical section showing a toilet mounted in a wall space;

Fig. 2 is an enlarged transverse sectionA taken as indicated on line 2-2 of Fig. 1v

Fig. 3 is a plan' taken as indicated by line 3-3 of Fig. 1;

Fig. 4 is an enlarged sectional detail taken as indicated by linea-4 on Fig. 2;

o f Fig 5 showing a sink inits normal position in a wall space.

In the drawings, referring first more par- 0.0 .ticularly to Figs. 1 to 4, the letter S represeiits the wall space within which the bowl B is adapted normally 'to stand, the two opsuitable closure, as by a small panelled oor 13, and the opening maybe surrounded by anysuitable case or triin as shown at 14; and all of these' features may be so designed wand constructed as to harmonizel with the interior nishof the room and so as effec tn ally to conceal the xture.

The outlet pipe for the bowl is shown at 2O leading to a trap 21 and thus connecting with the sewage system.l The inlet pipe is shownat 22. These two pipes extend in a horizontal direction and are arranged' on a common horizontal axis. `The outlet tube 23'cf the bowl connects b a swivelV jointr 24 rwith outlet pipe 20. e his swivel joint may be of any kind suitable for the purpose;

for instance, I show a packed joint; and it will beieadily' understood .how this kind' of joint allows the bowl to move between the positions shown in full and dotted lines in Fig. 1. At the inlet side a lsimilar swivel joint -25 l is used connecting the inlet tube 26 with inlet pipe 22. The supporting bearings for the bowl may be provided in any suitable mannen They may be provided by bearing supports that are independent ofthe inlet and Voutlet pipes, or they may be .provided through the medium of the pi es themselves. (For instance, at the outlet pipe I show the bowl outlet tube 23 having a supporting bearing in a bearing sleeve 27 that is con` nected with outlet pipe 2O and may be said to form a partr of the outlet pipe, and the outlet pipe and this part 27 are supported byv a supporting bracket 28 resting upon floor yF. At the inlet pipe I show inlet tube 26 having a direct bearing in su porting.

bracket 29 which stands upon the j oor. In 105 either case it will be seen that tliebowl can turn about the axisof the two pipes and that, whatever the position of the bowl the connection to both pipes is maintained.

The bowl here shown is preferably of a special construction, to be of as small depth as practicable and to provide for getting the iiushing water from the inlet pipe up to the upper edge of the bo-wl. vAround the inner upper edge of the bowl there is formed a water channel witha continuous opening or slot at 31 to discharge water at the upper edge of the bowl wall; and a passage y32 'leads from inlet tube 26 to this channel 30.

. The bowl is so constructed that its lowermost part, when lin either positionleads directly into the .outlet tube 23 as can be seen Jfrom consideration of Figs. .1 and 2; so that the bowl can be completely flushed. The outlet when the bowl is put back into the wall; and

a small guard wall at 36 prevents any water being splashed out of the bowl as it is put back into normal position.

- When the bowl is down, in the position yshown in dotted lines in Fig-1, it may be supported by any suitable supporting means. Various such means may Jbe used: I here merely show a sim le supporting means that is formed by the oor 13 resting on what is in eiiect the base board, or bottom` board of the casing or trim, as shown at 40.

I prefer, in my installation as here described, to use an automatic flushing valve that may be placed. in` water pipe 41 as indicated at 42. The stem 43 of this valve may project inwardly toward the bowl and there be provided with a handle-44 for its operationY to supply liusliing water. I also provide automatic means to flush the bowl 4automatically when it is put back to its normal position. This means may, for instance, be supplied in the manner shown in detail in Fig. 4..

An arm 45 is mounted on the tube' 26and swings with that tube when the bowl is swung between its two positions. This arm carriesat its outer end a pawl 46 that is normally held in the position shown in Fig.

n 4 by a suitable spring 47 a stop 48 serving to limit the spring pressed movement of the l pawl. As thebowl is put back4 into the wall this pawl 46 catches on an arm 48 ythat depends from valve stem 43, and as the pawl swings toward the position shown in dotted lines in Fig. 4, the arm'48a is moved back to the position shown in dotted lines. At

Lacasse this position the pawl passes beyond the arm; and thesubsequent automatic action of the flushing valve 42 throws the arm 48,

.and the handle 44, back to the position shown in full lines in Fig. 4, when the predetermined quantity of water has been supplied to the bowl. When the bowl is again lowered, the pawl 46 wipes under the arm 48a and then springs up to the position shown in full lines in Fig. 4 ready for the next automatic operation, of the flushing valve when the bowl is put back in the wall. Thus lI provide not only armeans whereby the bowl may be flushed at will, butl also a means whereby the bowl must necessarily be flushed as it is put back in the wall.

In Figs. 5 and 6 I show the same scheme applied toy a sink or similar article. The sink is shown at 50; the drain pipe at 51, and the water inlet pipe at 52. The valve 53, controlling the water supply, may have a handle 54 extending out through the wall face 12, in a position close to the sink.v In-` let and outlet tubes 26 and 23 may be su ported in bearing brackets 29 and 28. T e swivel joints are shown at 24 and 25. The inlet and outlet pipes-are here, as in the other construction, mounted on a common horizontal axis and are located at the lower back corner of the sink, as is apparent from Figs.v 5 and 6. The door 13, attached to the bottom of the sink, closes the wall opening when the sink is in the wall space. The wall supply to the sink may of course flow directly onto. its bottom through inlet 26. Or I may use a small water spout 3()a connected to the water passage 32 which connects with water inlet 26; to supply water at or near the upper edge of the sink ina convenient position for such operations as are usually carried on in a sink.

Having described apreferred form of my invention, I claim:

-1.' In combination, a tiltable bowl, inlet andv outlet pipes therefor located on a common horizontal-axis, swivel joints between the bowl and pipes so that the bowl maytilt on the'pipefaXis between a substantially horizontaljand a substantially vertical position; a trap in the outlet pipe, and the rear `end of the bowl having a wall that forms with the bottom and back wall, when the bowl is tilted up, a water container that holdswater at a level as high as the trap level.

2. In combination, a tiltable bowl, inlet and outlet pipes therefor located on a common horizontal axis, swivel joints between the bowl and pipes so that the bowl may tilt on the pipe axis between a substantially horizontal and a substantially vertical position; a valve cont-rolling the inlet pipe, and automatic means to operate the valve asthe bowl is swung to vertical position ;I atrap in the outlet pipe, and the rear end of the bowl having a wall thatforms with the bottom and back wall, when thebowl is tilted up, a water container that holds water at a level as high as the trap level.

3, In combination, an op'en topped water containing member adapted to swing be-y tween substantially horizontal and/vertical positions, an inlet and an outlet pipe on a common horizontal axis located and connected to the member near its back lower Corner, swivel connections between the member and the two pipes on which swivels the member swings, and means to control admission of water to the member throu h the inlet pipe when the member is in eit er of its positions, the rear end of the member having' an upper wall lthat forms with the bottom and back wall, when the member is tilted up, a water containing chamber.

In witness that I claim the v'foreqoin'g IL have hereunto subscribed my name, this 27 -day of July, 1922.
